      Hello Sabin, I love your channel and what you share. I'm a working Timber Wright and have built several of these types of bridges over the years. I've never been sure why they get called a "Da Vinci" bridge since the Chinese Scholar Lu Ban (魯班) was the first I've known of to employ a "stitch bridge" almost a thousand years before Da Vinci even lived. Some to these did span further and at a lower angle. Though made of stone, the Anji Bridge (安濟橋;) during construction employed these very same timber joinery systems and understanding, and still centuries before Da Vinci...Thanks again for what you and your team share and do with your videos...

One thing is clear. This bridge will never fail because of the joint issue. More the force you apply the stronger the joints become. Yah, of couse if any of the members of this bridge fails, the entire bridge will collapse at once.

    0:12 incorrect. There is a threshold of weight at which the structure cannot longer support. It is not possible to put infinite weight on the structure. There is a point at which the weight will not only weaken, it will deconstruct the structure.

    • @Nobody-iy6tm
      @Nobody-iy6tm Месяц назад +4

      Actually the construction is one of the methods to build an arch.
      Stress of materials can be loaded in a) compression, b) tension, c) shear.
      Stone and other materials are usually strong against compression, and less strong against tension and shear. Half circle ach is designed in a way that materials are compressed, which make the construction very stable.
      The Leonardo self supporting bridge is excellent construction when building a stable bridge with least materials.
      Another method would require huge amount of woods, but we can also build classic arch out of woods, in which woods are just compressed. The construction would then far more stronger than Leonardo self supporting bridge, while it is also self supporting. (We cannot build stable circle, though.)

    Although da Vinci is often given credit for this, the Chinese Emperors were building bridges like this a good period prior; some of it had to do with seasonal flooding problems that often took out small to medium sized bridges- the Emperor kept an inventory of these parts, these logs, and shipped them to where ever they were needed. First they were erected , then spanned, followed by a more reasonably sloped on side and off side to anchor it and make it usable.

    I have known about this bridge for some time and have experimented with various iterations of it.
    Everyone looks upon it as an arch bridge and for that it is brilliant.
    One thing I tried, is to build it upside down i.e. an inverted arch.
    As an inverted arch it can be rocked on the arch provided that each end is kept loaded toward the ground. To a limited extent it can be used to lower a load over a gap. As a form of crane
    Extending it is easy and can be done very quickly as the outer end is held in place by gravity so no need to support.
    Limited by the strength of the first beams as the load on them increase exponentially if pivoted at or close to the end

    @simonbrierley8488 День назад

    Thanks for publicising the forgotten design idea. I had never head of it before.
    With perfectly strait structurally components. The arch of the bridge is defined by the relations of the length and diameter of the of span components to diameter of the cross components. This understanding leads to several option to lengthen the span without scaling the components proportionally . Option 1 make the cross pieces thinner, possibly by notching them or using small diameter ones. The components are in compression and do not need to span such long distance so can be smaller anyway. Option 2 reduce the diameter or the span components where the meet the cross braces again using a notch or different material. Using notches will increase the friction and make the bridge more robust against a piece coming lose. Option 3 use curved span components. Components that curve in the opposite direction to the arch by some fraction. This happens in the video when the bridge flex under load, but this could an engineered choice. Are there any more options?

  • @ZyphisV

  • @LegoLapBlitz-jh3pb

    It is a really good experiment, but the issue is if you are using different pencils for the experiment (not sizes) shapes, like circular shaped pencils will easily slip, etc. But note it will be hard to make with pencils only and if it is not working and the result is not a bridge it must be because of the versatility of the pencils and the bridge. You can add toothpicks to strengthen your bridge but eventually, the pencils are ok my model could hold up to around 4 kgs just with the pencils but that's not too much weight, if you want to make your model really strong you can strengthen the green pieces by choosing strong wood or strong pencils mentioned in (1:02) part of the video, there is a disadvantage in the bailey bridge too, Even though it is temporary and it is costs less. The metal is mostly copper. Copper can easily rust and eventually, cracks are spotted so the bridge collapses if weight is kept onto after excessive usage. So Bailey bridges have an advantage and disadvantages😄! Mr. Sabin, this is a really informative video and I liked your animation and construction module. Thanks for the experiment once again!!!

    2:46 All the weight you apply will be transferred onto the density of the red pencils. They can also not be pulled outwards due to being inside a triangle; as soon as any one is removed it comes apart.*
    Securitisation changes, in the office model the top piece is not in a triangle and spreads out the structure making a wider curve; also a lower bridge.

    Very interesting. This could be used for a number of interesting applications honestly.
    The only way I can see it used in it's bridge form to lengthen it besides using it in those manners would be to try to interlock them using maybe two half circles. I would have to test on smaller scale.
    It seems it has a lot of potential outside of bridge use though.
    For example, it seems it would be advantageous in survival scenarios to know how to create this bridge, or use cordage to create a full circle, turn it sideways, maybe stack a couple. It could give you a cylindrical shelter. There's a lot of potential with it. 😊

    I know a compromise solution to the last problem: suppose the issue is the weight the bridge would have to carry. We can put bars nailed together over the entire river that can carry at least one person at a time. The person goes on the unsupported Bars until it's about the middle of the River, then the person has to ram a support tower into the riverbed, from the upside of the bridge. Now you can bed two Da Vinci bridges onto the support in the middle of the river. Use strings to support the horizontal bars. How exactly you get the support into the middle of the River is of less importance, you could use a boat aswell, once it's there you can save on many supports by using two or more Da Vinci bridges.

    This bridge model good for trap purpose. 5:43 If want to make it more steady maybe chain each poles of each junctions to make sure no pole edge or a log removed by accident.

    Amazing da vinci idea but instead of wood try some low weight but strong material and circular wheels that float and join all floating circles with rope and make a plank over that for a temporary floating but rigid bridge, excellent demonstration video, you tube needs such video to show potential of video demonstration of powerful ideas easily, if alive today, Leanardo davinci would have used RUclips very well to improvise his ideas

    To be honest you're idea was good, all we need to do is to keep that in place by adding something to each joint or to the whole structure, to prevent it from being pushed by the current cover it in a net like cover to let the water pass through but keep the thing intact.

  • @kobi2187

    I think the main interest from practical point is how to use them as scaffold, for building a stone arc or other structures. In that case, using ropes is not a bad idea, as both ropes and wooden bars are lightweight and can be assembled quickly.

    Set the supports on piles that rise out of the water. I think the Romans actually used this type of bridge on campaigns but they built a proper top deck.

    5:38 I think to elongate the bridge is to rope together a pair of wood into a wide v shape and replace that as the supporting sides of the bridge. potentially even flattening the bridge into a self supporting ladder-like appearance. look at how curved the pieces are at 1:54 and you can see the what I'm talking about

    The other advantage of the Bailey bridge is that it is flat, making it much easier to walk across and move rolling stock.

    They should use this on the parts of the Appalachian trail where small bridges were destroyed. This wouldn’t do much for cars and bikes, but it would be great for hikers on the trail.

    East Asia was using this technique for hundreds of years before Davinci. People think he invented the ideas he illustrated, completely unaware that he was reading about them in a library.

    I just tried this with pencils, but they keep slipping away.
    The animation has smooth materials, that should have the same problem.
    When Im constructing the bridge, I can see how it should work, that it is possible. I think some sandpaper can fix the problem, but I am Dutch, I dont want to waste 9 pencils.
    Am I doing something wrong, or is the animation kinda misleading?

    So... to actually use this incredible, no nails, no fastenings bridge, all you have to do is fasten all the parts together with rope first.
    Or make a different bridge first to get to the other side so you can use this bridge.
    Wow, what an amazing invention.

  • @Perfect-24

    The solution lies in twisting the bridge to cancel out the curvature. The minimal self-supporting & self-locking structure is the PENTAHELIX, that is a lateral frame expansion of the Tetrahelix

    What is the longest Da Vinci's Self Supporting Bridge you've heard of?
    Grok
    The most famous version of Leonardo da Vinci's self-supporting bridge is the proposal he made in 1502 to Sultan Bayezid II of Constantinople (present-day Istanbul) to span the Golden Horn. This bridge was designed to be 240 meters long and 24 meters wide, which would have made it the longest bridge in the world if it had been built.
    It is also worth mentioning that a modern version of this design, called the Vebjørn Sand da Vinci Project, was built in Norway over the E18 highway in Ås, in 2001. This bridge is 109 meters long with a main span of 40 meters, making it a of the longest built according to Da Vinci's design principles.
